Board Identification and Connector Layout

The pictured RJ003A has two black connector housings identified on the PCB as P1 and P11. Visible matching points include the connector contact arrangement, printed position numbers, four mounting holes, and notches along the board outline.

The reverse side shows RJ003A / BN634B561G51A, along with the separate PCB marking BN634B561H01. Compare the complete set of markings and both connector faces with your original assembly when selecting a replacement.

Product Scope

This listing covers the PCB and its fitted connectors. Any additional cables, mounting hardware, or accessories must be confirmed in your quotation. Actual-unit photos will identify the supplied configuration.

Fitment Confirmation

Send clear photos of both sides of your existing board, the connector contacts, all identification markings, and the equipment nameplate. Include any fault details. Connector appearance alone does not establish the pin assignment or replacement suitability.
